CORTEX BIOCHEM is a primary manufacturer; we market a broad range of antigens which are applicable for use in in-vitro research, product development, and manufacturing. CORTEX BIOCHEM utilizes state-of-the-art purification techniques to manufacture products of the highest quality, consistency, and integrity. Where applicable, multiple grades of purified antigens are available.

The ultra-purified and purified antigens are suitable as immunogens or can be used as reference materials. The semi-purified and purified antigens can be used for the manufacture of controls and calibrators. These products are supplied in bulk quantities or in research packaging to meet the needs of both the manufacturing industry and the research community. Most products are supplied "off-the-shelf" and can be produced to custom specifications. These products are not intended to be used for in-vivo human applications.

CORTEX BIOCHEM's broad range of antigen products offer you the convenience of a "one-stop" antigen source, backed by outstanding technical expertise and customer service.
